Type:  Adverb (Real scalar)
Use:   Limits the function to the AIPS number specified.  The "AIPS
       number" of a program is the (extended hexadecimal) number
       attached to its name when it is executed (values from 1 to
       Z).  Thus, AIPS2 has AIPS number 2, AIPSBF has AIPS number 15,
       and APCLNB has AIPS number 11.  Interactive AIPS can have AIPS
       numbers between 1 and NA, where NA is set locally.  The Checker
       program AIPSC for AIPSn uses AIPS number n.  The batch
       preparation program uses NA+1 and batch jobs use NA+1+NQ, where
       NQ is the batch queue number.
Null value:  0
      Null value means the current AIPS number.
      -1 means all AIPS numbers.
Verbs:
  PRTMSG.....Print selected contents of the message log file.
  CLRMSG.....Delete selected contents of the message log file.
